The UV resistance for improving product keeps it with low uncertainty according to the value of chromatism before and after shining in UV；In this way, it can be improved for workpiece
Sun-proof performance, color homogeneity provide technical support.
In one embodiment, step S101 can specifically include: sulfate be added in the second dyeing liquor, to obtain
The additive amount of one dyeing liquor, sulfate is greater than 0.5 gram per liter of second dyeing liquor.
Sulfate is generally rarely employed in workpiece dyeing industry as coloration additive, even with addition concentration
Also the effect for not exceeding 0.5g/L, and adding sulfate is different from the effect of sulfate in the application, in present embodiment
In, the effect of sulfate is added, is so that the first dyeing liquor is carried sulfonic group, and then increase dye molecule to form sulfonic group
Solubility, improve acid, and utilize to provide technical support for the sun-proof performance of workpiece raising, color homogeneity.The sulphur of addition
Hydrochlorate may is that sodium sulphate, potassium sulfate, lithium sulfate, etc..
When the sulfate of addition is solid sulfate salt, additive amount is greater than 0.5 gram per liter second dyeing liquor, such as: 1g/
L, 2g/L, 3g/L, 4g/L, 5g/L, etc..Certainly, in practical applications, sulfate liquor can also be added, additive amount needs

Wherein, the range of the additive amount of sulfate is 3-6 gram per liters of the second dyeing liquor.High concentration is added in staining trough
Sulfate can obviously change the Dye Adsorption process of workpiece surface epithelium, can effectively improve the anti-uv of workpiece
Energy.The addition of the sulfate of high concentration simultaneously, can obviously extend the adsorption process of dyestuff, so that upper Color uniformity mentions
Height solves the problems, such as workpiece surface Local Coloring unevenness.In one embodiment, the additive amount of sulfate is 3-6g/L, such as:
3g/L, 4g/L, 5g/L, 6g/L, etc..
By taking the staining reaction process of sulfate acid dyes as an example, high concentration sodium sulfate, sulfate radical are added in staining trough
Concentration increases, and reduces migration velocity of the dye molecule to oxidation layer surface, but also the ions binding process of dyestuff and epithelium
Forward reaction rate reduces, then when up to identical dye level is caused, needs to lengthen dyeing time.On the one hand can guarantee in this way
The uniformity of coloring solves the problems, such as that workpiece dyeing is uneven.On the other hand, dyeing course lengthens, and dyestuff can be enhanced in epithelium
Interior adsorptivity increases Dye Adsorption saturation degree.The change of dyestuff adsorbed state in film layer, so that product is in QUV aging
